A friend of mine has an 03 R6 that he dropped in a wheelie gone bad. It was at a rather low speed and the tank got a softball sized dent in it. Other than that the bike is in good shape and has about 2000 miles. I'm thinking about buying it but i don't know how much it should be worth considering the damage. Is there anythig else that i should look at due to the fact that it was dropped?
